'WHEEL Application filed (letoher 25, 19152.

To all whom it may concern lie it known that l, dosnri-I 'i. ltrNnA, acitizen oi the United States, and a resident et New Prague, in thecounty of Scott and State of Minnesota, have invented certain new andusefulImprovements in -Wheels, ot which the following is aspecilication, reiterence being had to the accompanying drawings.

rlhis invention has relation to certain new and useful improvements inwheels used in connection with automobiles, carriages and wagons; andthe object of my invention is to provide a spring vehicle wheel, ofsimple and durable construction, including a yieldingly secured outershock absorbing rim and certain peculiar spring holding` mechanisms.

Another object is to pro-vide a vehicle Wheel including a system ofresilient shock compensating members which can be readily removed and.replaced.

With these and other objects in view, the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described and iinally pointed out in the appended claims, it beingfurther understood that changes in the specic structure shown anddescribed may be made within the scope of the claims without departingfrom the spirit of the invention.

ln the accompanying drawings forming a part of this specication and inwhich like numerals of reference indicate similar parts in the severalviews: Figure 1, shows a plan view of a Wheel constructed accordingto myinvention with parts removed. Fig. 2, shows a section on line 2, 2 etFig. 1.

ln my present invention l provide a cushion or shock absorbing springwheel, the aim of the invention being to provide a wheel to replace thepneumatic tire wheel.

ln carrying out the object ot my inven tion I employ a hub 10. To thishub l secure a plurality of stub spokes 11, these spokes being securedto an inner rim 12.

As shown in lT ig. 1, interposed between each set ci stub spokes 11 is aprojecting spoke 13, these projecting spokes passing through suit ableopenings within the inner rim 12. At their ends these projecting1 spokesare apertured to receive the bolts 11i.

Disposed between the stub and projecting spokes, are a plurality etguide bars 15, one of which is shown in detail in Fig. 2. EachSpecification of Letters Patent.

guide bar has a stop shoulder 1G held upon the outer tace et the innerrim, each guide bar-being secured by means of a suitable nut 17. i-leldslidahly upon the outer end ol' each guide bar 15, is a grooved slideblock 1S, each slide block having its opposite face grooved, as is shownat 19.

lin connection with my `wheel l employ what l term an outer flanged rim23, having the oppesitely disposed tlanges 2liwhich are directed awayfrom the hub, as is shown in F ig. 2. 'llhese flanges 2d are reinforcedby means of the brace rims 25 and 26. is shown the outer flanged rim 23has a slot 9 arranged to accommodate the guide bars 15. Each guide bar15 is provided with a coil spring 8 passing through a slot 9, and at oneend pressing against a slide block 18 and at the opposite end restingagainst a stop sheulder 1G as shown in Fig. 2.

Secured to the liange 2d is what l term the major tire case 20, used inmy invention having the outstanding spurs 6. rihis major tire case 20has its edge 21 apertured and provided with a plurality oi screws 22, sothat this major tire case 20 may be secured to the minor tire casesection 5, the edge ot which is provided with screw openings arranged toreceive the screws 22.

fis disclosed in the drawings, the major tire case section 20 as well asthe minor tire case section has an inwardly directed reetangular bead d,these beads l being arranged to slide within the grooves 19. Se cured tothe inner tace of the major tire case section 20, at suitable points arethe angle braces 29, to which are liked the posts 30, each post having ahead 33, giving sup port to a suitable bolt 31.

Held upon the bolts lil, secured to the end ot the projecting spokes 13are the slide bars 28 each slide bar at its end having a slot 2?,arranged to receive a bolt 31, and interposed between the ends of theprojecting spokes 13 and the heads 33 are the springs 32.

Freni the foregoing it will be understood that the outer 'flanged rim ispermitted a movement independent ot the inner rim 12, in that thegrooved slide blocks 1S arev movably secured to the grooved blocksthrough the intermedium of the major and minor tire case sections. Asthe slide bars 28 further are permitted a tree movement at their ends,the slide blocks are also permitted to operate independent of the outerflanged rim 23. This is also true of the guide bars l5, whichreciprocate within the slots 9.

From the foregoing it will be understood that when a wheel constructedaccording t0 my invention encounters an obstruction, the shock will bepartially or wholly absorbed by means of the springs 8 and 32.

A wheel constructed according to my invention is simple andcomparatively inexpensive and both durable and efficient in operation,and the working parts may bc readily replaced in case of fracture.

Having thus described my said invention what I claim is:

l. A spring wheel having in combination, a hub a plurality of stubspokes extending from said hub, an inner rim secured to said spokes, aplurality of projecting spokes eX- tending from the hub and beyond saidinner rim, a plurality of guide bars secured to said inner rim andextending beyond the same, a grooved slide block held upon each guidebar, an outer flanged riln, said guide bars extending through said rim,a plurality of slide bars pivoted to the ends of said projecting spokes,a tire casing secured to said outer rim said tire casing having inwardlydirected beads engaging said slide blocks, a spring upon each guide barcontacting with a slide block, a plurality of posts secured t0 saidcasing, said slide bars being slidably secured to said posts, and aspring held upon each slide bar as and in the manner set forth.

2. The combination in a spring wheel of a pluralityv of stub spokes, aninner rim secured to said stub spokes, a plurality of guide barsextending from said inner rim, an outer apertured rim, said guide barseX- tending through the apertures of said outer rim, a collar secured toeach guide bar, a grooved slide block movably held upon each guide bar,a spring interposed between each slide block Vand against a collarsecured to each guide bar, and a tire case having inwardly directedbeads engaging within the grooves of said slide blocks as and in themanner set forth.

3. A spring wheel provided with a plurality of stub spokes, an inner rimsecured to said stub spokes, a plurality of projecting spokes passingthrough said inner rim, an outer tire case, a plurality of posts securedto said outer tire case directed inwardly, two oppositely directed slidebars secured to the end of each projecting spoke, said slide bars havingslotted ends, a bolt secured to each post arranged to receive theslotted ends of said slide bars, and a spring upon each slide bar allarranged substantially as and for the purpose set forth. A

In testimony whereof I affix my signature, in the presence of twowitnesses.
